2 Claims.

This invention relates to certain new and usel ul improvements in a battery clamp and deals particularly with a type of structure which is simple in construction, easy to apply to the terminal of an electric battery and very efficient in Another object of the invention is the provi-- sion of a split clamp, the parts of which are so interconnected as to prevent complete disassemoiage and possible loss of some of the parts when the clamp is in opened condition.

A still further object of the invention is the provision of a clamp which can be applied to battery terminals of various diameters.

These and other objects will readily present themselves when the following specification is read in connection with the attached drawing wherein there is shown the preferred embodiment of the invention. In the several Views depicted in the drawing, similar letters of reference indicate like parts throughout the several views wherein:

Figure l is a pian View of the clamp in applied position on a terminal post of a battery.

Fig. 2 is a longitudinal section of the clamp shown in Figure 1.

Fig. 3 is a view similar to Figure l, but showing the clamp in loosened condition about the terminal of the battery post.

Fig. l is a side elevation of the clampas shown I in Figure l.

Fig. 5 is a longitudinal sectional'view of the clamp.

` Fig. 6 is an end view of the clamp as shown in i Figure 1.

In the drawing, a fragmentary part of a storage battery is suggested at l and the battery is provvided with an end terminal or post 2. The application of battery clamps to the terminal post 2 has been accomplished in a vast number of ways, some of which are of the split type and others of It has been found very nal clamps from the battery post, especially if the same had been applied for a considerableV period of time, and then again corrosion rhas often acted as a hindrance to the removal of the clamp. In all cases of removal of lthe solid or ring type, a prying or wedging action, or a series of forcible blows must be applied to the underside of the ring to loosen the same from the post.

Damage has often been incurred either vto the body portion of the battery or the post, and in some instances to the clamp itself by such .forceful removal. In the split type of clamps, the mode of removal from the post is extremely simplied, but in case the locking or fastening screw is removed, the sections of the clamp fall apart, in which condition some portion of the clamp is apt to become misplaced or in some instances lost. l

In the present invention itis therefore the main object to provide a split clamp with some means of retaining the loosened sections or parts in a somewhat assembled condition so as to prevent complete disassemblage and possible loss of some of the parts. This split clamp is composed of parts 3 4, each part having an arcuate face 5, the face being tapered, if desired, as suggested in Figure 5, to fit about the periphery of the batterypost 2. Also each of the vparts 3--4 have 4a perforated ear 6 through which the fastening bolt freely passes. A clamping nut 8 is threadedly engaged with one end of a bolt 'l to accomplish the tightening of the clamp when it is desired to fasten the same to the battery post 2. One of the parts as suggested, may have a shoulder 9 formed thereon to provide a seat for the head of the bolt 'l to prevent turning of the bolt during the fastening of the clamp.

The part 3 is provided with an extension l0 which constitutes the means for attaching the wire or cable to the clamp. This extension l0 may loe of solid formation as suggested, and the K wire or cable may be fastened thereto in any suitable manner, or if desired, the extension may be socketed as at il Figure 5, for the reception of one end of a wire or cable and fastened into said socket by a screw l2.

The part 4 is provided with a terminal loop or eye I3 which is adapted to fit over the extension Iii thereby-forming a connection between the two separable parts 3 and 4. Even if the bolt 'l is entirely removed, the parts 3 and 4 will be retained in a somewhat assembled relation due to the connection afforded by the loop I3 with the extension I0.

While we have described above and disclosed in the attached drawing the preferred embodiment of the invention, it is to be understood that various vmodifications or changes in construction may be resorted to without departing from the spirit of the invention.

What we desire to claim is:

1. A battery clamp comprising two opposed gripping members each having a curved bodyportion with an arcuate inner face to t the post of a battery, one of said members having a Wiresecuring terminal extending longitudinally therefrom, the other of said gripping members having a reduced terminal portion curved in conformity with the end of the opposed gripping member to form a seat therefor, said reduced portion having an opening therein to encircle the Wire-securing terminal of the opposed gripping member, and aclamping bolt to draw the gripping members in applied position on the battery post.

2. A battery clamp comprising two opposed `a looped extension curved in conformity with the end portion of the opposed gripping member to snugly t the exterior curved face thereof and to encircle the Wire-securing terminal, and a clamping member to draw the opposed gripping 1o members in applied position on the battery post.
